Independent generation of the iminyl (X = N) and pyrrol-1-yl (X = N) radicals by flash vacuum pyrolysis of the corresponding oxime ether and N-(dimethylamino) compound, respectively, provides two regioisomeric pyrrolo1,2-A]quinoxalines compounds. This shows that the radical species interconvert via the spirodienyl moeity at high temperatures. Corresponding generation of the pyrrol-1-yl (X = CH) radical gives the pyrrolo[1,2-A]quinoline as the only cyclised product. In this case, DFT calculations suggest that direct cyclisation of the pyrrol-1-yl takes place, rather than formation of the spirodienyl species and exclusive migration of the C-N bond.

This study introduces an efficient method for the selective formylation of indoles and pyrroles at the positions of C(3) and C(2), respectively. The mixture of three equivalents of N,N-dimethylformamide and one equivalent of 2,4,6-trichloro-1,3,5-triazine (cyanuric chloride) generates an easy handling formylating agent for the efficient formylation of these classes of compounds to give the corresponding aldehydes under mild reaction conditions. This procedure was highly efficient, and a range of formylated indoles and pyrroles were obtained in good to excellent yields.

Mild acid treatment of alcoholic solutions of Stenhouse salts has been shown to yield a mixture of the corresponding N-arylpyrrole-2-carbaldehyde and the N-aryl-3-hydroxypyridinium salt.Treatment of alcoholic solutions of the Stenhouse salts with a variety of bases leads to 4-substituted 2-arylaminocyclopent-2-enones.
